Multiplatinum-selling hip-hop duo Outkast will perform at the eighth annual Treasure Island Music Festival, the two-day celebration of indie-rock, electronic music and more set for Oct. 18-19 on Treasure Island.

The festival's lineup also includes such popular acts as Massive Attack, Zedd, Alt-J, TV on the Radio and Janelle Monae.

A limited number of two-day "early bird" tickets priced at $145 go on sale at 10 a.m. June 19. Two-day regular admission tickets are $160 and a two-day VIP ticket costs $295. Two-day parking passes are $70. For more information, visit http://treasureislandfestival.com/2014/.

No word on when -- or if -- single-day tickets will go on sale.

Outkast is arguably the biggest attraction on this year's bill.

The reunited hip-hop duo has been making the rounds at many major festivals, including performing at last month's BottleRock Napa Valley, where Outkast thrilled a huge crowd with such longtime fan favorites as "So Fresh, So Clean," "Ms. Jackson" and "Hey Ya!"

The bill for last year's Treasure Island included Atoms for Peace, Beck, Animal Collective, Major Lazer, James Blake, Little Dragon, Sleigh Bells, Phantogram and the Japandroids.
